Love the clock, still play white noise on top of that, so audio stacking could be cool.
Would also be great if there was a voice that said 5 mins left
What would be really super is if the intensity of the clock sound picked up or intensified at set intervals, similar to the british tv show countdown
in short
White noise is a MUST
Clock intensity is a MUST (As an option obviously)
the rest is lest important
love the app, its brilliant
